Description

Technical Field

[0001] The present application relates to the technical field of new material detection, and in particular to a high-boiling silicone oil viscosity detection device and a detection method thereof. Background Art

[0002] High-boiling silicone oil, whose chemical name is methylmethoxysilane mixed copolymer, is an organic silicon material among advanced polymer materials. It has the characteristics of high heat resistance, electrical insulation, hydrophobicity, etc. It appears as a colorless or light yellow transparent oily liquid and can usually withstand high temperatures of 200℃-300℃.

[0003] The viscosity of silicone oil is also called viscosity. Measuring the viscosity of high-boiling silicone oil mainly depends on understanding its rheological properties to meet the requirements of different applications. There are many measurement methods for high-boiling silicone oil viscosity detection, such as: capillary viscometer method, rotational viscometer method, falling ball method, oscillation viscometer method, etc. Among them, the rotational viscometer method is to connect the corresponding model of rotor to the bottom shaft of the controller, pour a certain volume of silicone oil to be tested into the sample cup, and use the lifting controller to make the groove on the rotor just flush with the upper surface of the silicone oil. When the rotor rotates in the silicone oil, the silicone oil will produce resistance to the rotor. The resistance is proportional to the viscosity of the liquid. The viscosity of the liquid can be calculated by measuring the torque or speed. After the measurement, the rotor and sample cup need to be cleaned in detail.

[0004] The viscosity of silicone oil decreases with increasing temperature. When testing the viscosity of high-boiling silicone oil, more temperature gradients need to be measured. During the measurement, the silicone oil must be kept at a specified temperature, that is, the temperature of the sample cup is controlled by the electric heater of the high-temperature viscometer, and the temperature fluctuation in the sample cup must be kept within ±0.1°C.

[0005] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: after each test is completed, the controller needs to be raised to unscrew the rotor, remove the sample cup, and then the silicone oil on the surface of the rotor and the sample cup needs to be cleaned with paper towels, rags and other tools. Since this process is often carried out when the rotor and the sample cup are still at high temperatures, the staff needs to take insulation measures. The process is relatively cumbersome and has great safety hazards. During the heating and insulation process of the silicone oil, the heating of the electric heater is relatively uneven, which can easily cause large local temperature fluctuations. Summary of the invention

[0006] In order to improve the problems of the rotor and the sample cup being difficult to clean and the silicone oil being unevenly heated, the present application provides a high-boiling silicone oil viscosity detection device and a detection method thereof.

[0007] The present application provides a high boiling silicone oil viscosity detection device adopts the following technical solution: A high-boiling silicone oil viscosity detection device and a detection method thereof, comprising a frame, a controller threadedly raised and lowered on the frame, a rotating shaft rotatably connected to the bottom of the controller, a rotor threadedly connected to the free end of the rotating shaft, and a sample cup placed on the frame, characterized in that: a heating barrel containing heat-conducting oil is arranged on the frame, a cup groove adapted to the sample cup is provided on the heating barrel, a material leakage port is provided at the bottom of the sample cup, a mounting cylinder is rotatably connected to the frame below the sample cup, a support plate adapted to the material leakage port is movably provided on the mounting cylinder, a receiving groove for receiving the support plate is reserved between the heating barrel and the mounting cylinder, and an adjustment mechanism for adjusting the position of the support plate is provided on the mounting cylinder; The mounting tube is provided with two air pipes connected to an air source, the air pipes are sleeved with air bags, and the mouth of the air bags is seamlessly fixed to the air pipes, a high-elastic sponge is provided on the surface of the air bags, a rotating assembly for driving the mounting tube to rotate is provided on the frame, and a cleaning assembly for cleaning the high-elastic sponge is provided on the mounting tube; The sample cup is also provided with a cup cover, the cup cover is provided with a through groove whose width is greater than the rod diameter of the rotor, and the through groove extends from the edge of the cup cover to the center of the cup cover, and the frame is provided with a monitoring component for monitoring the relative height of the silicone oil in the sample cup.

[0008] By adopting the above technical solution, the silicone oil to be tested is poured into the sample cup, the rotor is threadedly connected to the shaft so that the rotor faces the sample cup, and then the height of the controller is adjusted to adjust the height of the rotor. At the same time, the height of the silicone oil liquid level relative to the controller is monitored in real time through the monitoring component. Since the positions of the grooves of the rotor are all standard values, the position of the silicone oil liquid level on the rotor can be displayed through the conversion of the controller until the liquid level is flush with the grooves of the rotor. The cup cover is covered and the rotor is passed through the groove to reduce the heat loss in the sample cup; the heating barrel is turned on to make the sample cup evenly heated by the heating barrel. After heating for a specified time, the temperature of the heating barrel is kept unchanged, and the rotor is rotated by the controller. After the rotor rotates for a specified time, the viscosity value of the silicone oil of this model at this temperature can be detected; by adjusting The mechanism moves the support plate downward, at which time the silicone oil leaks out from the leakage port, and then the support plate is further moved and the air pipe is raised to allow the air bag to enter the sample cup, and then air is blown through the air pipe to expand the air bag until the high-elastic sponge is close to the inner wall of the sample cup. The rotating part rotates the mounting cylinder, thereby driving the high-elastic sponge to rotate and remove the residual silicone oil in the sample cup. After the high-elastic sponge is removed, the air bag is contracted and the air pipe is lowered. During this process, the cleaning component cleans the silicone oil on the high-elastic sponge in time, and finally the support plate is returned to the initial position through the adjustment mechanism, and the viscosity detection operation of the next batch can be carried out. This process can be fully autonomously operated through the program pre-set by the controller, which greatly shortens the steps of manual cleaning and reduces safety hazards. The heating barrel heated by thermal oil is more uniform and stable than the heating of an electric heater.

[0009] Optionally, the adjustment mechanism includes a screw rod rotatably connected to the mounting tube, an adjustment block threadedly connected to the screw rod, a baffle fixedly connected in the mounting tube, and an adjustment motor fixedly connected to the bottom of the baffle, the adjustment block is fixedly connected to the bottom of the support plate, and the adjustment mechanism is also provided with a conversion component for controlling the control block to switch between two states of vertical movement and horizontal rotation with the screw rod as the center. When the adjustment block moves down to abut against the baffle, a gap is provided between the support plate and the sample cup for silicone oil to pass through.

[0010] By adopting the above technical solution, when the silicone oil in the sample cup is detected, the adjustment motor drives the screw to rotate, and the conversion component limits the control block to move only in the vertical direction. That is, in this process, the screw drives the adjustment block to move downward, and then the support plate moves downward until the adjustment block and the baffle are against each other. At this time, the silicone oil leaks out from the leakage port, and the support plate is shielded above the high-elastic sponge to prevent excessive silicone oil from falling on the high-elastic sponge; after the silicone oil has leaked out, the conversion component limits the control block to rotate only with the screw as the center, and then the adjustment motor continues to drive the screw to rotate, so that the support plate enters the receiving groove to prevent the support plate from interfering with the high-elastic sponge to enter the sample cup.

[0011] Optionally, the conversion assembly includes a long limit plate and a short limit plate fixedly connected to the mounting cylinder, the long limit plate and the short limit plate are parallel to the screw rod, the gap between the short limit plate and the baffle plate is adapted to the adjustment block, and when the screw rod drives the adjustment block to descend, the short limit plate is located on the side facing the direction of the adjustment block's tendency to move in the horizontal direction.

[0012] By adopting the above technical scheme, when the support plate is located at the leakage port, the screw rod rotates, and the adjusting block is limited by the long limit plate and the short limit plate, so that the adjusting block can only descend. When the adjusting block is against the baffle plate and the screw rod continues to rotate in the aforementioned direction, the bottom of the adjusting block is blocked by the baffle plate and rotates until the support plate enters the accommodating groove; when the support plate needs to be returned to the leakage port, the adjusting motor drives the screw rod to rotate in the opposite direction, and the top of the adjusting block is blocked by the short limit plate and can only move in the direction close to the long limit plate. When the adjusting block moves to against the long limit plate, the adjusting block is blocked by the long limit plate and moves upward until the support plate moves to the leakage port and the adjusting motor stops. The structure is simple and the stability is high.

[0013] Optionally, the monitoring component includes a laser emitter fixedly connected to the bottom of the controller, a refractive photosensor fixedly connected to the bottom of the support plate, and a reflective photosensor fixedly connected to the bottom of the controller, the laser emitter obliquely illuminates the silicone oil surface, the reflective photosensor and the laser emitter are symmetrical with respect to the normal of the light emitted by the laser emitter on the silicone oil surface, and the support plate is made of transparent material.

[0014] By adopting the above technical solution, the laser emitted by the laser transmitter is refracted and reflected when it is irradiated on the liquid surface. The refracted laser is received by the refractive photosensor, and the reflected laser is received by the reflective photosensor. When the distance between the liquid surface and the laser transmitter changes, the position of the light spot received by the refractive photosensor and the reflective photosensor also changes accordingly. If the refractive index of the silicone oil of this model is known, the dual monitoring of the refractive photosensor and the reflective photosensor is more accurate. If the refractive index is unknown, the position of the liquid surface can be known through the reflective photosensor, and the refractive index of the silicone oil can also be reversely inferred in conjunction with the refractive photosensor.

[0015] Optionally, the cleaning assembly includes a brush ring rotatably connected to the mounting tube, a brush fixedly connected to the inner wall of the brush ring, a plurality of nozzles fixedly connected to the inner wall of the mounting tube, a gear ring fixedly connected to the outside of the brush ring, and a cleaning motor fixedly connected to the mounting tube, the nozzle is opposite to the brush, and the gear ring is meshingly connected to the output end of the cleaning motor.

[0016] By adopting the above technical solution, when the airbag shrinks and the trachea moves downward, the cleaning motor drives the gear ring to rotate, and the brush ring rotates accordingly, so that the brush on the brush ring continues to remove silicone oil and other substances adsorbed on the high-elastic sponge. During this process, the nozzle also sprays clean water on the brush to improve the cleaning degree of the high-elastic sponge. At the same time, a small amount of silicone oil on the high-elastic sponge and in the sample cup falls on the gear ring, which can also lubricate the gear ring.

[0017] Optionally, a liquid supply pipe is fixedly connected to the cup cover, and a plurality of nozzles are fixedly connected to the bottom of the cup cover and communicated with the liquid supply pipe.

[0018] By adopting the above technical solution, when the high-elastic sponge cleans the sample cup, the liquid supply pipe delivers the cleaning agent, so that the nozzle sprays the cleaning agent downward to improve the cleaning degree of the high-elastic sponge; when the high-elastic sponge has finished cleaning, the liquid supply pipe can also spray clean water to the cup wall of the sample cup, so that the mixture of silicone oil, cleaning agent, etc. remaining on the sample cup by the high-elastic sponge is cleaned by the clean water, further improving the cleaning degree, and because the temperature of the sample cup is relatively high, the water stains remaining in the sample cup can evaporate in a very short time.

[0019] Optionally, the connection between the inner bottom wall of the sample cup and its inner peripheral wall is a smooth chamfer, and the inner bottom wall of the sample cup is funnel-shaped.

[0020] By adopting the above technical solution, the chamfer of the sample cup reduces the dead angles encountered when the high-elastic sponge is cleaned, and the funnel-shaped inner bottom wall facilitates the liquid in the sample cup to leak out from the leakage port.

[0021] Optionally, a plurality of elastic drawstrings are connected inside the airbag and between the branch pipes.

[0022] By adopting the above technical solution, when the bronchus rotates, the elastic drawstring provides multiple force points for the airbag, so that the airbag can move more smoothly.

[0023] A method for detecting the viscosity of high-boiling silicone oil comprises the following steps: S1. Pre-test sequence: put the silicone oil to be tested into the sample cup, and then use the monitoring component to monitor the position of the silicone oil liquid level on the rotor in real time, and adjust the height of the controller in real time to control the height of the rotor until the groove on the rotor is at the silicone oil liquid level, and then cover the sample cup with a cup cover and turn on the heating barrel for heating; S2. Formal test: After the heating barrel is heated to the specified temperature, keep the heating barrel at this temperature, and control the rotor to rotate through the controller. After the rotor rotates completely, the controller displays the viscosity value of the silicone oil at this temperature; S3. Cleaning: After the test is completed, the support plate is lowered through the adjustment mechanism to allow the silicone oil to leak out from the leakage port. After most of the silicone oil has leaked out, the support plate is allowed to enter the receiving tank through the adjustment mechanism, and the air pipe is raised to allow the air bag to enter the sample cup. The air pipe is then deflated to allow the high-elastic sponge on the surface of the air bag to cling to the inner wall of the sample cup. The mounting cylinder is rotated to allow the high-elastic sponge to scrape off the silicone oil adhering to the sample cup. Finally, the air pipe is retracted, the high-elastic sponge is cleaned through the cleaning component, and the support plate is returned to its original position.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. Move the support plate downward through the adjustment mechanism. At this time, the silicone oil leaks out from the leakage port. Then move the support plate further and raise the air pipe to allow the air bag to enter the sample cup. Then blow air through the air pipe to expand the air bag until the high-elastic sponge is close to the inner wall of the sample cup. The rotating part rotates the installation cylinder, which drives the high-elastic sponge to rotate and remove the residual silicone oil in the sample cup. After the high-elastic sponge is removed, shrink the air bag and lower the air pipe. In this process, the cleaning component cleans the silicone oil on the high-elastic sponge in time, completing a full-process cleaning. There is no need for much manual intervention during cleaning, and the cleaning is relatively simple and safe. 2. When the silicone oil needs to be heated and kept warm, cover the cup lid, pass the rotor through the slot, turn on the heating barrel, and evenly heat the sample cup by the heating barrel. After heating for a specified time, continue to keep the temperature of the heating barrel unchanged, thereby completing the heating and insulation of the silicone oil. The heating method of the heating barrel with thermal oil is more uniform and stable than that of the electric heater. 3. The laser emitted by the laser transmitter is refracted and reflected when it hits the liquid surface. The refracted laser is received by the refraction photosensitive sensor, and the reflected laser is received by the reflection photosensitive sensor. When the distance between the liquid surface and the laser transmitter changes, the position of the light spot received by the refraction photosensitive sensor and the reflection photosensitive sensor also changes accordingly. If the refractive index of the silicone oil of this model is known, dual monitoring by the refraction photosensitive sensor and the reflection photosensitive sensor is more accurate. If the refractive index is unknown, the position of the liquid surface can be known through the reflection photosensitive sensor, and the refractive index of the silicone oil can also be reversely inferred in conjunction with the refraction photosensitive sensor. 4. When the airbag contracts and the trachea moves downward, the cleaning motor drives the gear ring to rotate, and the brush ring rotates accordingly, so that the brush on the brush ring continues to remove the silicone oil and other substances adsorbed on the high-elastic sponge. During this process, the nozzle also sprays clean water on the brush to improve the cleaning degree of the high-elastic sponge. At the same time, a small amount of silicone oil on the high-elastic sponge and in the sample cup falls on the gear ring, which can also lubricate the gear ring. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The mounting tube 2 is connected with a main pipeline connected with an air source through a cylinder lifting device, and the main pipeline is connected with two air pipes 41. An air bag 42 is sleeved on the air pipe 41, and the mouth of the air bag 42 is seamlessly fixed to the air pipe 41. A high-elastic sponge 43 is arranged on the surface of the air bag 42. A rotating assembly 8 for driving the mounting tube 2 to rotate is arranged on the frame 1. The rotating assembly 8 includes a rotating motor 81 fixed to the frame 1 and a gear ring 82 fixed to the bottom of the mounting tube 2. The output end of the rotating motor 81 is meshed and connected with the gear ring 82. A cleaning assembly 5 for cleaning the high-elastic sponge 43 is arranged on the mounting tube 2; a cup cover 142 is also placed on the sample cup 14, and a through groove 1421 with a groove width greater than the rod diameter of the rotor 13 is opened on the cup cover 142, and the through groove 1421 extends from the edge of the cup cover 142 to the center of the cup cover 142, and a monitoring assembly 6 for monitoring the relative height of silicone oil in the sample cup 14 is arranged on the frame 1.

[0031] Pour the silicone oil to be tested into the sample cup 14, thread the rotor 13 onto the rotating shaft 12, make the rotor 13 face the sample cup 14, then adjust the height of the controller 11 to adjust the height of the rotor 13, and monitor the height of the silicone oil liquid level relative to the controller 11 in real time through the monitoring component 6. Since the positions of the grooves of the rotor 13 are all standard values, the position of the silicone oil liquid level on the rotor 13 can be displayed through the conversion of the controller 11 until the liquid level is flush with the grooves of the rotor 13, cover the cup cover 142, and make the rotor 13 pass through the groove 1421 to reduce the heat loss in the sample cup 14; turn on the heating barrel 15, so that the sample cup 14 is evenly heated by the heating barrel 15, and after heating to the specified time, continue to keep the temperature of the heating barrel 15 unchanged, and at the same time, rotate the rotor 13 through the controller 11. After the rotor 13 rotates for the specified time, the viscosity value of the silicone oil of this model at this temperature can be detected; through the adjustment mechanism 3, the support plate 21 moves downward, at this time, the silicone oil leaks from the leakage port 141, and then the support plate 21 is further moved, the air pipe 41 is raised, the air bag 42 enters the sample cup 14, and then the air bag 42 is expanded by blowing air through the air pipe 41 until the high elastic sponge 43 is close to the inner wall of the sample cup 14, and the rotating part rotates the mounting cylinder 2, thereby driving the high elastic sponge 43 to rotate and remove the residual silicone oil in the sample cup 14. After the high elastic sponge 43 is completely removed, the air bag 42 is contracted and the air pipe 41 is lowered. In this process, the cleaning component 5 cleans the silicone oil on the high elastic sponge 43 in time, and finally the support plate 21 is returned to the initial position through the adjustment mechanism 3, and the viscosity detection operation of the next batch can be carried out. This process can be fully autonomously operated through the program pre-set by the controller 11, which greatly shortens the steps of manual cleaning and reduces safety hazards. The heating barrel 15 heated by thermal oil is more uniform and stable than the heating of the electric heater.

[0032] Reference Figure 3The adjusting mechanism 3 includes a screw rod 31 rotatably connected to the mounting tube 2, an adjusting block 32 threadedly connected to the screw rod 31, a baffle 33 fixedly connected to the mounting tube 2, and an adjusting motor 34 fixedly connected to the bottom of the baffle 33. The adjusting block 32 is fixedly connected to the bottom of the support plate 21. The adjusting mechanism 3 is also provided with a conversion component 35 for controlling the control block to switch between two states of vertical movement and horizontal rotation with the screw rod 31 as the center. When the adjusting block 32 moves down to abut against the baffle 33, there is a gap between the support plate 21 and the sample cup 14 for silicone oil to pass through. The conversion component 35 includes a long limit plate 351 and a short limit plate 352 fixedly connected to the mounting tube 2, the long limit plate 351 and the short limit plate 352 are both parallel to the screw rod 31, the gap between the short limit plate 352 and the baffle plate 33 is adapted to the adjustment block 32, and when the screw rod 31 drives the adjustment block 32 to descend, the short limit plate 352 is located on the side facing the direction of the adjustment block 32 moving in the horizontal direction. In the present application, a scraper 9 is also fixedly connected to the end of the short limit plate 352, so that the scraper 9 can scrape off the silicone oil on the support plate 21 when the support plate 21 enters the receiving groove 22.

[0033] When the support plate 21 is located at the leakage port 141, the adjusting motor 34 drives the screw rod 31 to rotate, and the adjusting block 32 is limited by the long limit plate 351 and the short limit plate 352, so that the adjusting block 32 can only go down. When the adjusting block 32 abuts against the baffle plate 33, the silicone oil leaks from the leakage port 141, and the support plate 21 is shielded above the high-elastic sponge 43 to prevent excessive silicone oil from falling on the high-elastic sponge 43; then, when the screw rod 31 continues to rotate, the bottom of the adjusting block 32 is blocked by the baffle plate 33 and rotates until the support plate 21 enters the receiving port. The groove 22 is formed to prevent the support plate 21 from interfering with the high-elastic sponge 43 from entering the sample cup 14; when the support plate 21 needs to return to the leakage port 141, the adjusting motor 34 drives the screw rod 31 to rotate in the opposite direction, and the top of the adjusting block 32 is blocked by the short limit plate 352 and can only move in the direction close to the long limit plate 351. When the adjusting block 32 moves to abut against the long limit plate 351, the adjusting block 32 is blocked by the long limit plate 351 and moves upward until the support plate 21 moves to the leakage port 141, and the adjusting motor 34 stops. The structure is simple and the stability is high.

[0034] Reference Figure 4 The monitoring component 6 includes a laser emitter 61 fixedly connected to the bottom of the controller 11, a refraction photosensor 62 fixedly connected to the bottom of the support plate 21, and a reflection photosensor 63 fixedly connected to the bottom of the controller 11. The laser emitter 61 obliquely irradiates the silicone oil liquid surface, and the reflection photosensor 63 and the laser emitter 61 are symmetrical with the normal line of the light emitted by the laser emitter 61 on the silicone oil liquid surface. The support plate 21 is made of high-transmittance and low-reflection glass.

[0035] The laser emitted by the laser transmitter 61 is refracted and reflected when it is irradiated on the liquid surface. The refracted laser is received by the refractive photosensor 62, and the reflected laser is received by the reflective photosensor 63. When the distance between the liquid surface and the laser transmitter 61 changes, the position of the light spot received by the refractive photosensor 62 and the reflective photosensor 63 also changes accordingly. If the refractive index of the silicone oil of this model is known, the dual monitoring of the refractive photosensor 62 and the reflective photosensor 63 is more accurate. If the refractive index is unknown, the position of the liquid surface can be known through the reflective photosensor 63, and the refractive index of the silicone oil can also be reversely inferred in cooperation with the refractive photosensor 62.

[0036] Reference Figure 2 and Figure 3 The cleaning assembly 5 includes a brush ring 51 rotatably connected to the mounting tube 2, a brush 52 fixed to the inner wall of the brush ring 51, a plurality of nozzles 53 fixed to the inner wall of the mounting tube 2, a gear ring 54 fixed to the outside of the brush ring 51, and a cleaning motor 55 fixed to the mounting tube 2. The nozzle 53 faces the brush 52, and the gear ring 54 is meshed and connected with the output end of the cleaning motor 55. When the airbag 42 contracts and the air pipe 41 moves downward, the cleaning motor 55 drives the gear ring 54 to rotate, and the brush ring 51 rotates accordingly, so that the brush 52 on the brush ring 51 continuously removes the silicone oil and other substances adsorbed on the high-elastic sponge 43. In this process, the nozzle 53 also sprays clean water on the brush 52 to improve the cleaning degree of the high-elastic sponge 43. At the same time, a small amount of silicone oil on the high-elastic sponge 43 and in the sample cup 14 falls on the gear ring 54, which can also lubricate the gear ring 54.

[0037] Reference Figure 2 The cup cover 142 is fixedly connected with a liquid supply pipe 71, and the bottom of the cup cover 142 is fixedly connected with a plurality of nozzles 72 which are connected with the liquid supply pipe 71. When the highly elastic sponge 43 cleans the sample cup 14, the liquid supply pipe 71 delivers a cleaning agent, and the nozzles 72 spray the cleaning agent downward to improve the cleaning degree of the highly elastic sponge 43; when the highly elastic sponge 43 has finished cleaning, the liquid supply pipe 71 can also spray clean water to the cup wall of the sample cup 14, so that the mixture of silicone oil, cleaning agent, etc., which remains on the sample cup 14 by the highly elastic sponge 43, is cleaned by the clean water, further improving the cleaning degree, and because the temperature of the sample cup 14 is relatively high, the water stains remaining in the sample cup 14 can evaporate in a very short time.

[0038] Reference Figure 3A plurality of elastic drawstrings 421 are connected between the airbag 42 and the branch pipe. The connection between the inner bottom wall of the sample cup 14 and its inner peripheral wall is smoothly chamfered, and the inner bottom wall of the sample cup 14 is funnel-shaped. When the bronchial tube 41 rotates, the elastic drawstrings 421 provide multiple force points for the airbag 42, so that the airbag 42 can move more smoothly. The chamfer of the sample cup 14 reduces the dead angle encountered by the high-elastic sponge 43 when cleaning, and the funnel-shaped inner bottom wall facilitates the liquid in the sample cup 14 to leak from the leakage port 141.

[0039] The implementation principle of a high-boiling silicone oil viscosity detection device in an embodiment of the present application is as follows: pour the silicone oil to be tested into the sample cup 14, thread the rotor 13 onto the rotating shaft 12, so that the rotor 13 faces the sample cup 14, and then adjust the height of the controller 11 to adjust the height of the rotor 13, and turn on the laser generator at the same time. The laser emitted by the laser transmitter 61 irradiates the liquid surface and refracts and reflects. The refracted laser is received by the refraction photosensitive sensor 62, and the reflected laser is received by the reflection photosensitive sensor 63. When the distance between the liquid surface and the laser transmitter 61 changes, the positions of the light spots received by the refraction photosensitive sensor 62 and the reflection photosensitive sensor 63 also change accordingly. Based on this principle, the controller 11 can display the position of the silicone oil liquid surface relative to the groove of the rotor 13.

[0040] When the liquid surface is flush with the groove of the rotor 13, the cup cover 142 is put on and the rotor 13 is passed through the through groove 1421 to reduce the heat loss in the sample cup 14, and then the heating barrel 15 is turned on to make the sample cup 14 evenly heated by the heating barrel 15. After heating for a specified time, the temperature of the heating barrel 15 is kept unchanged, and the rotor 13 is rotated by the controller 11. After the rotor 13 rotates for a specified time, the viscosity value of the silicone oil of this model at this temperature can be detected.

[0041] After the detection is completed, the stepping motor drives the screw rod 31 to rotate, and the adjusting block 32 is limited by the long limit plate 351 and the short limit plate 352, so that the adjusting block 32 can only descend. When the adjusting block 32 is against the baffle plate 33, the silicone oil leaks from the leakage port 141, and the support plate 21 is shielded above the high-elastic sponge 43 to prevent excessive silicone oil from falling on the high-elastic sponge 43; then, when the screw rod 31 continues to rotate, the bottom of the adjusting block 32 is blocked by the baffle plate 33 and rotates until the support plate 21 enters the receiving groove 22.

[0042] Then, the air pipe 41 is raised to allow the air bag 42 to enter the sample cup 14, and air is blown through the air pipe 41 to expand the air bag 42 until the high-elastic sponge 43 is closely attached to the inner wall of the sample cup 14. The rotating assembly 8 rotates the mounting cylinder 2, thereby driving the high-elastic sponge 43 to rotate and remove the residual silicone oil in the sample cup 14, and the nozzle 72 also sprays the cleaning agent into the sample cup 14. After the high-elastic sponge 43 has been cleaned, the air bag 42 is retracted and the air pipe 41 is lowered, and the cleaning motor 55 drives the gear ring 54. The brush ring 51 rotates, and the brush ring 51 rotates accordingly, so that the brush 52 on the brush ring 51 continuously removes the silicone oil and other substances adsorbed on the high-elastic sponge 43. During this process, the nozzle 53 also sprays clean water for the brush 52 to improve the cleaning degree of the high-elastic sponge 43. At the same time, a small amount of silicone oil on the high-elastic sponge 43 and in the sample cup 14 falls on the gear ring 54, which can also lubricate the gear ring 54. Then the nozzle 72 sprays clean water to further remove the debris on the sample cup 14 and the rotor 13.

[0043] When the support plate 21 needs to return to the leakage port 141, the adjusting motor 34 drives the screw rod 31 to rotate in the opposite direction, and the top of the adjusting block 32 is blocked by the short limit plate 352 and can only move in the direction close to the long limit plate 351. When the adjusting block 32 moves to against the long limit plate 351, the adjusting block 32 is blocked by the long limit plate 351 and moves upward until the support plate 21 moves to the leakage port 141.

[0044] Embodiment 2

[0045] The present application discloses a method for detecting the viscosity of high-boiling silicone oil. Figure 1-4 , the high boiling silicone oil viscosity detection method includes the following steps: S1. Pre-test sequence: put the silicone oil to be tested into the sample cup 14, then monitor the position of the silicone oil liquid level on the rotor 13 in real time through the monitoring component 6, and adjust the height of the controller 11 in real time to control the height of the rotor 13 until the groove on the rotor 13 is located at the silicone oil liquid level, then cover the sample cup 14 with the cup cover 142, and turn on the heating barrel 15 for heating; S2, formal test: After the heating barrel 15 is heated to a specified temperature, the heating barrel 15 is kept at the specified temperature, and the rotor 13 is controlled to rotate by the controller 11. After the rotor 13 has completed rotating, the controller 11 displays the viscosity value of the silicone oil at the specified temperature; S3, cleaning: after the test is completed, the support plate 21 is lowered by the adjusting mechanism 3 to make the silicone oil leak out from the leakage port 141. After most of the silicone oil leaks out, the support plate 21 is allowed to enter the receiving groove 22 by the adjusting mechanism 3, and the air pipe 41 is raised to make the air bag 42 enter the sample cup 14. Then, the air pipe 41 is deflated to make the high-elastic sponge 43 on the surface of the air bag 42 close to the inner wall of the sample cup 14. The mounting cylinder 2 is rotated to make the high-elastic sponge 43 scrape off the silicone oil adhered to the sample cup 14. Finally, the air pipe 41 is retracted, and the high-elastic sponge 43 is cleaned by the cleaning component 5 and the support plate 21 is returned to its original position.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
